Upon thinking about this again I am not 100% sure these are black market.
These lenses may very well be immediate post-war lenses when any materials and working tools must have been incredibly scarce.
Not enough black paint for the name ring, or perhaps the oven that was used to bake that paint was taken or destroyed, and basically making do with whatever materials were on hand - so junkers, experiments and parts that previously failed QA got repurposed. The nickel plated mount may very well be an experiment before they transitioned fully into the new chromed shape, etc.
The aperture gripper is too shallow and has too many ridges, yes - but once again this may have been a previously failed part lying around in some bin. For example you could imagine the ridges had cracked or the tool had slipped during machining. Then upon re-purposing it to make these "Frankensteins" the solution was to cut the cracked/failed bit off and make a shallower grip.
